A week after being trounced by Brad Lander in the fight to replace City Councilmember Bill de Blasio in the 39th District, the Republican candidate is still sending out e-mail press releases demanding answers for — at least in his eyes — campaign shenanigans.

Most recently, Nardiello gave new meaning to the word nit-picker by accusing the Lander campaign and his supporters from the Working Families Party (WFP) for putting out a campaign mailing without indicating who had paid for it.

“Countless 10,000s of registered Democrats received a postcard mailing days before Election Day to vote on the Working Families line when voting for Democratic candidate Brad Lander,” he said. “Who paid for this? Nowhere on the postcard mailing does it say ‘paid for by.’”

Nardiello, who now considers himself to be “a new and critical voice on the Brooklyn political scene,” has asked the Campaign Finance Board to look into the matter.

“Should we all simply accept that the Working Families Party is allowed to play by its own set of rules?” Nardiello asked. “Is fair for third parties to pay for candidate mailings without so much as telling our voters where the message or money is coming from?”

But Nardiello didn’t have to get the Campaign Finance Board involved. All he had to do was ask Lander, who freely admits that his campaign paid for the mailing.

“It was from us,” he said. “It’s got my logo and address and our committee name on it. We paid for it, but it didn’t go out to tens of thousands of people, it went to about 5,000.”

Lander said that he put out the mailing to show his support for paid sick leave legislation and other WFP issues.

The city councilmember-elect wouldn’t comment on Nardiello’s accusations.

“I’m excited to be getting to work,” he said.

Lander won the November 3 general election by securing 15,279 votes — over four times the number that Nardiello did on the Republican line (he secured second place with 3,650 votes).

In the final days before the election, Nardiello raised eyebrows by putting 7,000 fliers warning about an upcoming “parking permit tax.” Everyone noticed the campaign fliers, which were disguised as parking tickets.

The stunt even got the attention of New York magazine, which recently mentioned the act in the “despicably lowbrow” section of their Approval Matrix page, right above “Jessica Simpson’s blasting of Melrose Place for crap writing.”

“This is the closest I’ve been to Kate Winslet and Jessica Simpson,” Nardiello said.
